Shallow water equations are widely used in inundation analysis and they are known to be successful in computation of floods over wide terrains. Flood propagation in between buildings in urban areas and flows around hydraulic structures such as bridges may not satisfy the assumptions of shallow flow and may display markedly more 3-Dimensional (3D) flow characteristics. However, for the convenience of fast numerical solutions, the shallow-current equations can also be used for such 3D flows and useful output may be obtained.
